Yamaha YXZ1000R / Textron Wildcat XX Camshafts
BC Brian Crower Yamaha YXZ, Arctic Cat / Textron Wildcat XX camshafts are brand new, semi finished, induction hardened cam cores made from SAE 1050 steel that allows the capability to grind unlimited lobe specifications while still maintaining the factory base circle size. Up until this point, camshaft options available for the Yamaha YXZ, Arctic Cat / Textron Wildcat XX were regrinds cut from stock cam cores, which greatly restricts the amount of lift and duration possible due to base circle limitations, or expensive hardfacing or hard welding of stock cam cores. While hardfacing does allow for unlimited spec, you're at the mercy of these "welded up lobes" holding up over time and if they don't, you've got debris in your engine. Producing cams from billet round bar is an overkill process and an expensive alternative to the BC cam production process, which delivers OEM quality cores ground with high performance lobe profiles. The Yamaha YXZ1000R 1000R engine platform is a liquid-cooled, 998cc, 12-valve, double-overhead-cam, inline triple cylinder with 172 horsepower. The 900cc displacement features a bore size of 80mm (3.150"), a stroke of 66.2mm (2.606") and 11.3:1 compression ratio and dry-sump. A fully automatic, dual-range, belt-type continuously variable transmission, the Yamaha YXZ1000R 1000R engine offers exceptional power, a thrilling 10,500 rpm redline, and high-strength internals ready to handle the demands of high-output modifications like turbocharging.
